An amino acid is
The basic building block of proteins (or polypeptides).
An anticodon is
The three-base sequence in tRNA complementary to a codon on mRNA.
An autosome chromosome is
Any chromosome that is not a sex chromosome.
A catalyst is
A substance that increases the rate of a chemical reaction without itself being permanently changed.
In DNA the quantity of adenine equals the quantity of thymine and the quantity of guanine equals the quantity of cytosine.

This is known as ________ rule
Chargaff's rule
The site of crossing-over between homolgous chromosomes is known as a
A codon is
A sequence of three RNA or DNA nucleotides that specifies (codes for) either an amino acid or the termination of translation.
The term used to describe the correspondence of DNA bases such that adenine in one strand is opposite thymine in the other strand and cytosine in one strand is opposite guanine in the other is
complementarity or complementary DNA sequence.
The loss of a DNA (chromosome) segment from a chromosome is known as a _____________ mutation
Denaturation of DNA is
The separation of the two strands of a DNA double helix.

The first step in a PCR reaction, or in any DNA replication.
DNA (deoxyribonucleic acid) is
he fundamental substance of which genes are composed.
A DNA fingerprint is
The largely individual-specific banding pattern produced when DNA is digested with a restriction endonuclease, and a Southern blot is probed and developed.
An enzyme that closes nicks in one strand of double-stranded DNA is
DNA Ligase
An enzyme that can synthesize new DNA strands using a DNA template is
DNA polymerase
A mutation in which there is an addition or deletion of one, two or a small number (not a multiple of three) of nucleotides that causes the codon reading frame to shift
A frameshift mutation
The type of replication that human DNA undergoes during S-Phase of the cell cycle
semi conservative
An enzyme that opens up the DNA double helix for replication
Differences between DNA and RNA
Double or Single Strand
